Fry-01944526 Patented July 29, 1941 UNITED STATES PATENT OFFICE2,250,675 l V ARBOR FOR srooLson THE LIKE George B. Markle, Jr.,Hazleton, Pa. Application April 20, 1940, Serial No. 230,793 Claims.(01. 242-134) This invention relates to arbors for spools or the like,and is a companion application of my application filed of even dateherewith, the object being to provide an arbor so constructed that twoarbors can be employed for supporting a spool of any length.

Another object of my invention is to provide an arbor which isexceedingly simple and cheap in construction and yet durable in use.

Another object of my invention is to provide an arbor having a shoulderto form a stop, or a support for the spool to limit the inward movementof the arbor into the spool.

Other and novel features of the invention will be hereinafter set forthin the appended claims.

In the drawing Figure 1 is a side elevation of a pair of arbors partlyin section arranged in a spool;

Figure 2 is a detail end view;

Figure 3 is a side elevation of a modification;

Figure 4 is a detail end view of the construction shown in Figure 3;

Figure 5 is a side elevation partly in section of another modifiedconstruction of arbor;

Figure 6 is an inside face view of the head shown in Figure 5.

In the embodiment of my invention, as shown in Figures 1 and 2, I employa central metal core I, preferably tubular in form, on which is Weldedadjacent one end a head 2 composed of a circular metal disc which isbent back upon itself, as shown at 3, and then outwardly to form anannular laterally projecting supporting flange 4 spaced from peripheryof the head to form a stop shoulder 5 for the shell 6, as shown indotted lines in Figure 1 in placing the shell in position on the arbor.The flange is herein shown formed continuous, but it can be formed of aplurality of sections, as shown in the embodiment of my invention, asshown in Figures 5 and 6, to form supporting surfaces for the free endsof the wire. In either construction, a lateral supporting surface isformed for connecting the ends of the wires to the head. While the headis shown spaced from the end of the core, it can be flush with the endof the core, as shown in another embodiment of my invention.

One end of the core is provided with cross slots 1 and 8, in which arearranged substantially U-shaped resilient wires 9 and I0, provided withbowed arm portions 9 and I0 extending towards the head, having their endportions extending through apertures 4' formed in the flange 4, theextreme ends being bent at right angles, as shown at II, to secure thebowed wires in their proper position therein. This provides a simpleconstruction to frictionally support a shell or spool thereon by theresiliency of the bowed wires. The bowed wires present inclined surfacesto the inner wall of the shell in positioning a shell thereon to preventthe shell from being injured. The shoulder or stop 5 limits the inwardmovement of the arbor into the shell. It is of course understood that asingle arbor could be used for supporting a shell in a verticalposition.

In the embodiment of my inventipn, as shown in Figures 3 and 4, l2indicates a tubular core having a head l3 secured thereon, constructedas disclosed in Figures 1 and 2. Arranged on the core are the open ringportions l4 formed in substantially U-shaped resilient wires l5 and I6,which are provided with bowed arms I5 and I6, having their free endportion extending through apertures formed in the flange [3' of thehead, the extreme ends being bent at right angles, as shown at IT, forretaining the wires therein.

In the embodiment of my invention, as shown in Figures 5 and 6, 18indicates a tubular core on which is secured a circular disc forming ahead IS, the peripheral edge being bent back upon itself, as shown at20, to strengthen the same. Punched inwardly from the face of the headare a plurality of sections 2|, forming supporting surfaces which areapertured to receive the ends of the wires 22, constructed as disclosedin Figures 3 and 4. As the wires have open ring portions they can besprung apart to allow them to be placed in position or removed from thecore and will be held in their proper position by the resiliency of thewires. The inner face of the head forms a stop for the shell to preventthe same from entering the shell too far. The central opening of thehead is provided with an annular flange 23 to embrace the core. I wishit to be clearly understood that the construction of wires disclosed inFigures 1 and 2 can be used with the construction of head disclosed inFigures 5 and 6, without departing from the spirit of my invention.

Under certain conditions, it has been found that an arbor constructed,as disclosed in this application, can be used to an advantage inconnection with the construction disclosed in my companion application330,792, filed of even date herewith.

What I claim is:

1. An arbor for spools or the like comprising a core, a head secured onone end of said core, U- shaped wires carried by the other end of saidcore, said head being provided with apertured lateral supportingsurfaces spaced from the periphery of said head, the free ends of saidwires being secured in the apertures of said supporting surfaces.

2. Supporting means for spools or the like comprising a pair ofduplicate arbors adapted to be placed in the respective ends of a spool,each arbor comprising a core having a head at one end provided withlateral projecting supporting surfaces spaced from the periphery of saidhead, U-shaped resilient wires carried by the other end of said corehaving their free ends mounted in said supporting surfaces, and meansformed on the ends of the wires for securingsaid wires in saidsupporting surfaces.

3. An arbor of the kind described comprising a core, a head secured onone end of said core provided with a lateral projecting apertured flangespaced from the periphery of said head,

U-shaped wires provided with open ring portion embracing said corehaving bowed arm portions extending through the apertures of saidflange, the ends of the wires being bent at right angles to position andhold said wires in said flange.

4. An arbor for spools comprising a core having slots in one endthereof, a head secured on the other end of said core provided withlateral apertured extensions, U-shaped wires mounted in the slots ofsaid core having bowed arms, the ends of said arms extending through theapertured extensions.

5. An arbor for spools comprising a core having a head at one end, andU-shaped wires at the other end, supporting surfaces carried by saidhead, the arms of said wires being connected to the supporting surfacesof said head.
